Mobile IPv6 is decoupled from any particular link layer, as it uses IPv6 Neighbor Discovery [12] instead of ARP. This also improves the robustness of the protocol. o The use of IPv6 encapsulation (and the routing header) removes the need in Mobile IPv6 to manage "tunnel soft state". o The dynamic home agent address discovery mechanism in Mobile IPv6 returns a single reply to the mobile node. The directed broadcast approach used in IPv4 returns separate replies from each home agent.
